Techniques for transmitting information using beacon symbols are described. A transmitter may map first information to at least one subcarrier in a first set of subcarriers, with the first information being conveyed by the position of the at least one subcarrier. The transmitter may map second information to one or more subcarriers in a second set of subcarriers. The second information may be conveyed by one or more modulation symbols sent on the one or more subcarriers. The transmitter may generate at least one beacon symbol having the first information mapped to the at least one subcarrier in the first set and the second information mapped to the one or more subcarriers in the second set. In one design, the transmitter may frequency division multiplex the first information with the second information. In another design, the transmitter may puncture the second information on the at least one subcarrier with the first information.
